Specification of Letters Patent.

Patented June 25, 1907.

Original application filed November 21, 1906, Serial No. 344,460. Divided and this application led January 23, 1907- Serial No. 353,583.

To @ZZ whom, t may concern:

Be it known that I, WILLIAM PRELLWITZ, a citizen of the United States, and a resident of Easton, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Roller- Guides for Channeling-Machines, of which the Jfollowing` is a speciiication.

The object of this present invention is to provide certain improvements in the construction, forni and arrangement of the several parts of a roller guide whereby the outer guide roller support may be made detachable; in which the inner guide roller is made plain for engaging the rear sides of the drill steels and the outer guide roller is made iianged for engaging the edges and front sides of the said drill steels; in which novel means are employed 'for oiling the guide rollers and in which novel means are employed for preventing the loss of the locking bolt and key when the outer guide roller support is detached from the inner guide roller support.

In the accompanying drawings, Figure 1 represents the roller guide in front elevation, Fig. 2 represents the same in side elevation, Fig. 3 is a vertical section taken in the plane of the line AHA of Fig. 2, looking in the direction of the arrows, Fig. 4 is a transverse vertical section taken in the plane of the line B-*B of Fig. 1, looking in the direction of the arrows, Fig. 5 is a horizontal section taken in the plane of the line C-C of Fig. 2, looking in the direction of the arrows, and Fig. 6 is a horizontal section taken in the plane of the line D-D of Fig. 2, looking in the direction of the arrows.

The inner guide roller support is denoted by 1 and the detachable outer guide roller support by 2. The inner plain guide roller is denoted by 3 and the outer flanged guide roller by 4.

The axle 5 for the inner guide roller 3 is secured at its ends within the support 1, and is provided with a longitudinal oil passage 6 extending from end to end therethrough. Thisoil passage has one or more branch ducts 8, 9, for feeding oil to the bore of the roller 3. Oil chambers 10, 11, are provided in the sides of the support 1, which chambers are in open communication with the passage 6 in the axle 5. These oil chambers 10, 11,

'may be filled through holes closed by the screw caps 12, 13. For more effectually and economically feeding oil to the bore of the roller 3, a piece of wicking 7 is passed through the passage 6 and has its ends coiled within the oil chambers 10, 11.

The axle 14 for the outer flanged guide roller 4 is secured at its ends within the detachable support 2 and is provided with a longitudinal oil passage 15 extending from end to end therethrough. This passage 15 is provided with one or more branch ducts 17, 18, for feeding oil to the bore of the roller 4.

Oil chambers 19, 20, are provided in the sides of the detachable support 2, which chambers are in open communication with the passage 15 in the axle 14. These oil chambers 19, 20, may be filled through holes# closed by the screw caps 21, 22.

For more eifectually and economicallyw feeding oil to the bore of the roller 4, a piece of wicking 16 is passed through the passage 15 and has its ends coiled within the oil chambers 19, 20.

The axles 5 and 14 are removably secured in position by providing locking bolts 23, 24, for impinging against the ends of the axle 5 and locking bolts 25, 26, for impinging against the ends of the axle 14. Screw caps 27, 28, are arranged in alinement with the axle 5 and screw caps 29, 30, are arranged in alinement with the axle 14 so that the said axles may be removed when released by their locking bolts, by a longitudinal movement in either direction.

The means which I have shown for detachably securing the outer guide roller support to the inner support is as follows Two locking bolts 31, 32, extend inwardly through the detachable support 2 and are provided at their inner ends with heads 33, 34, arranged to be dropped into enlarged portions 35, 36, of recesses opening through the top of the inner guide support, the re-A IOO into the said enlarged portions of the recesses.

The outer ends of the bolts are provided with elongated slots 39, 40, through which tapered locking keys 41, 42, extend, the inner faces of said keys being arranged to abut against the outer face of the outer guide roller support and the tapered front faces of said keys being arranged to engage the outer ends of the elongated. slots 39, 40, for forcing the two supports 1 and 2 snugly together as the keys are driven home.

To prevent the keys from dropping out and the bolts from being removed when the outer support is detached from the inne r support, I provide springs 43, 44, located in recesses 45, 46, surrounding the bolts 31, 32, which springs are interposed between the bottoms of said recesses and angular shoulders 47, 48, on said bolts.

rIhe heads 33, 34, of the bolts are preferably made round so that the bolts may be turned into any position to bring their keys into different angular positions as shown in dotted lines in Fig. 1.

To insure a perfect alinement of the axes of the two rollers when in operative position, the two supports are provided with an interlocking connection which is shown herein by providing the adjacent faces of the two supports 'with horizontal tongues and grooves.

Then it is desired to remove the drill steels, the keys may be released thus permitting the two supports to be separated by the withdrawal of the heads of the bolts from their recesses and the disengagement of the tongue and groove connection between the adjacent faces of the two supports.

By providing the roller guide with a plain inner roller and a fianged outer roller, it will be seen that the 'iianged outer r'oller may be removed with its support thus removing all restraint upon the drill steels in a lateral direction. This will vpermit the drill steels to be removed without having to be swung over the flanges of the roller as would be the case if the inner roller 'were provided with the fianges instead of the outer roller.

It will be seen that the springs 43, 44, will retain the keys within their elongated slots in the bolts when the outer support is detached from the inner support thus preventing the accidental loss of either the keys or the bolts from the said outer support.

It will furthermore be seen that ample provision is made for supplying oil to the rollers, in a very simple and effective manner.

It will also be seen that a very ready means of permitting the roller axles to be removed when so desired, is also provided.

Certain of the parts shown and described but not claimed herein form the subject matter of my application filed November 2l, 1906, Serial No. 344460, entitled Roller guides for channeling machines, of which application the present application is a division.
